To all whom it may concern: a

Be it known thatI, WILLIAM R. Gorgeou- ZOU, a citizen of the UnitedStates, residing at Baton Rouge, in the county of East Baton Rouge andState of Louisiana, have invented certain new and useful Improvements inHedge-Trimmers, of which thefollowing is a specification.

This invention relates to hedge trimmers and more 3 particularly toelectrically operated machines of this character.

The object of theinvention is to so construct an implement of thischaracter that it may be easily manipulated and which will accomplish amaximum amount of work with a minimum consumption of. time Anotherobject is toso construct an im lementof this character that it will belight and inexpensive to manufacture and which will occupy a small spacewhen not in use. b With the foregoing and other objects in view, whichwill appear as the. description.

proceeds, the invention resides in the combination and arrangement ofparts and in the details of construction, hereinafter described andclaimed, it being understood that changes in the precise embodiment .ofthe invention herein disclosed may be made within the scope of what isclaimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a plan view of a hedgetrimmer constructed in accordance with this invention,

Fig. 2 is a side elevation thereof,

Fig. 3 is a similar view taken from the side opposite to that shown inFig. 2,

Fig. 4 is a front elevation, and

Fig. 5 is a transverse section taken on the line 5-5 of Fig. 1.

In the embodiment illustrated a base plate 1 is shown having a fixedblade 2 carried by one side edge thereof and provided with cutting teeth3. This blade 2 is preferably made integral with the plate 1 as shown inFig. 5 and has a shoulder 4 at the base of its cutting teeth whichoperates as a guide for the movable blade 5 mounted to reciprocatelongitudinall on blade 2. This blade 5 also has teeth 6 w ich conform inshape and size to the teeth of blade 2 and are beveled as are deslthreade studs 9 WhlCh pro ect upwardly H Specification of LettersPatent.

Q11 and springs 12, the springs and washers being disposed between thenuts" and outer face of blade 5 as is shownclearly in Fig. 5. fExtending transversely of plate near the front end thereof is a shaft.13 mounted to rotate in standards 14, rising from plate 1 as is shownc'learly in Fig. '5. A pulley 15 is carried by one end of the shaft 13while 1 a crank disk 16 is carried by its other end and afiy wheel 17 isdisposed thereon between said pulley and crank disk. A wrist pin 18projects laterally and concentrically from theouter face of disk 16 andis en gaged with one endof a pitman 19, the

other end of said pitmanbein connected I with the movable blade 5 nearits rear end asis shownclearly in Fi s. 1, 2 and 4. The.

pit man 19 as shown in ig'. 1.is arranged longitudinally of said blade 5so that whenl the shaft 13 is turned, a reciprocatory motion willbeimparted to said blade, causing the cutting teeth .thereofto .slidablymove over the cutting teeth of the stationaryf blade 2 for trimmingrass, twigs'and the like with which the ev1ce is engaged.

A driving belt 20 passes around pulley 15 and over a cooperating pulley21 carried by a shaft 22 of an electric motor 23, said motor being suported in suitable bearings on plate 1. Tl'llS motor may be of anysuitable or desired construction and as the details thereof constituteno part of this invention they will not be herein described.

A switch 24 controlledby a push button 25 is mounted between two handles26 and 27 which roject laterally from one end of the base p ate 1,andthe switch is connected with the motor so that when the button isdepressed the motor will be started and the shaft 22 thereof rotated andthrough belt 20 will drive shaft 13 and reciprocate blade 5 to effect acutting operation.

The handles 26 and 27 are here shown arranged in diverging relationalthough obviously they need not be so positioned, but

such arrangement facilitates the operation of the machine enabling thehandles to be more readily grasped by both hands of the user., Thehandle 27 is shown disposed in a plane parallel with the cutting bladeswhile handle 26 is arranged at an oblique angle thereto to provide forthe easy and convenient manipulation of the trimmer and for thepositioning'between said hank dles of the switch operating push buttonso that it may be actuated by the thumb of either hand. I I

In the use of this device, the handles 26 and 27 are rasped .by bothhands of the operator so t at the push button 25 will be positioned fordepression by either thumb.

When this button is depressed, the switch is closed and the motor throwninto operation and it continues to rotate and oper-' atethe cuttingblade 5 until said button is released when it instantly stops. It willthus be seen that by actuating the cutting blades over the hedge to betrimmed, the

, twigs Will be cut and the surface maybe of time.

shaped to conform to the wishes of theop-' erator and owing to the rapidreciprocation of blade 5 under the action of the motor 23 a maximumamount of work may be accomplished with a minimum consumption From theforegoing description, taken in connection with the accompanying draw-'ings, the advantages of the construction and of the method of operationwill be readily apparent to those skilled in the art to which theinvention appertains and while I have described the principle ofoperation of theinvention together with the device which I now considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such chan es ma be madeas are within the scope o the c aimed invention.

I claim l. A trimmer of the class described comprising a base plate, astationary blade carried thereby, a movable blade -mounted toreciprocatethereon, iding means for said -movable blade carried by said fixedblade,

base to form a guide, a movable blade mounted to reciprocatelongitudinally on 'said'fixed blade and guided by said shoulder, saidmovable blade having lon 'tudinally extending slots therein, threadestuds I carried by said fixed blade and projecting through said slots,washers, springs an nuts on said studs for holding said movable blade inslidin relation on said fixed blade, I

and means or actuating said movable blade.

In testimony whereofI afiix my signature in presence of two witneses.
